Google Hangouts not allowing me to make outgoing calls

I got the newest version of Google Hangouts with dialer and Google Voice number but I can't make any phone calls out.I believe only messaging work.When I input number in dialer and it doesn't show up as a free or what it will cost to make call.Just numbers im a row.Is there a setting or it doesn't work on a Verizon LG G3 running Kit Kat.
